The Asetek water block can be bought for +- € 80, while this custom made CPU block cost less then half of that price!
Danger Den has a similar chipset water block which costs +- 40 €, but Danger Den products are hard to find in Belgium and if you want to order them yourself the shipping and taxes will cost you more then the cost of the block... same can be said for the VGA-block.
At the time of writings, this revision of home-made water blocks cost around 35 € each, not too expensive right?!

So, for these of us who live in Belgium, the Netherlands, or somewhere in the neighbourhood, these blocks are really worth your consideration.
